OCF_HEARTBEAT_RAID1(7) OCF resource agents OCF_HEARTBEAT_RAID1(7)NAMEocf_heartbeat_Raid1 - Manages Linux software RAID (MD) devices on
shared storage
SYNOPSIS
Raid1 [start | stop | status | monitor | meta-data | validate-all]
DESCRIPTION
This resource agent manages Linux software RAID (MD) devices on a
shared storage medium. It uses mdadm(8) to start, stop, and monitor the
MD devices. Raidtools are supported, but deprecated. See
https://raid.wiki.kernel.org/index.php/Linux_Raid for more information.
SUPPORTED PARAMETERS
raidconf
The RAID configuration file, e.g. /etc/mdadm.conf.
(required, string, no default)
raiddev
One or more block devices to use, space separated. Alternatively,
set to "auto" to manage all devices specified in raidconf.
(required, string, no default)
homehost
The value for the homehost directive; this is an mdadm feature to
protect RAIDs against being activated by accident. It is
recommended to create RAIDs managed by the cluster with "homehost"
set to a special value, so they are not accidentially
auto-assembled by nodes not supposed to own them.
(optional, string, no default)
force_stop
If processes or kernel threads are using the array, it cannot be
stopped. We will try to stop processes, first by sending TERM and
then, if that doesn't help in 3 seconds, using KILL. The lsof(8)
program is required to get the list of array users. Of course, the
kernel threads cannot be stopped this way. If the processes are
critical for data integrity, then set this parameter to false. Note
that in that case the stop operation will fail and the node will be
fenced.
(optional, boolean, default true)
SUPPORTED ACTIONS
This resource agent supports the following actions (operations):
start
Starts the resource. Suggested minimum timeout: 20s.
stop
Stops the resource. Suggested minimum timeout: 20s.
status
Performs a status check. Suggested minimum timeout: 20s. Suggested
interval: 10.
monitor
Performs a detailed status check. Suggested minimum timeout: 20s.
Suggested interval: 10.
validate-all
Performs a validation of the resource configuration. Suggested
minimum timeout: 5.
meta-data
Retrieves resource agent metadata (internal use only). Suggested
minimum timeout: 5.
EXAMPLE
The following is an example configuration for a Raid1 resource using
the crm(8) shell:
primitive p_Raid1 ocf:heartbeat:Raid1 \
params \
raidconf=string \
raiddev=string \
op monitor depth="0" timeout="20s" interval="10"
